When Burzum released Hvis Lyset Tar Oss in 1994, underground metal was forever split. This album featured longer songs where concept was closely intertwined with song structure, and riff shape defined by mood. It both made undone past paradigms and raised the bar.

After that point, black metal and death metal deflated. The initial rise of ideas created in reaction to outrage at a dying civilization was gone, and nothing else propelled the genre forward, so it fell into self-imitation based on outward traits. Further, few bands could handle the raised bar, so it was “explained away” in social circles and the music tended toward the more primitive, not less.

Thus is the problem with raising the bar. Once you have done it, people either rise to the challenge and forge ahead in the new language, or have to hide the fact that they’re here for the gravy train which means they want to make the same dumbass music they would make in rock, pop, punk or blues, but use some distortion and call it “black metal.” That leads to high margins: the product is cheap to make because it’s a well-known type, but it has a higher markup due to novelty.

However, unless you’re deaf, you’ve noticed that the output of underground metal has seriously flagged in quality since the mid-1990s. Not so in quantity, of course, where we have more bands than ever before who have better production, are better instrumentalists, and generally more savvy at the music industry. Unfortunately the music they produce is not as good as what a few lonely intelligent outcasts did in the early 1990s.

This leads us back to a question of metal’s growth. Do we keep up with the raised bar? Style is not substance, but the two are related. Without enough substance, style never evolves; without the right style, substance often gets lost. Artists tend to visualize the two at the same time as part of the same articulation of an idea that they are communicating through mood, or the sensation of perceiving something and wanting to engage with it. In theory, metal could continue with what it has, using the same styles but writing new music, and many bands have succeeded in that. But keeping up with the raised bar has some advantages.

First, instrumental metal would be difficult and this would draw a line between metal and the pop, rock, blues and rap and place us closer to ambient and classical in the respect scale. Take for example this quote from educator Liam Malloy:

“In the past, heavy metal has not been taken seriously and is seen as lacking academic credibility when compared with other genres such as jazz and classical music. But that’s just a cultural construction.”

Second, this change would get rid of the vocal problem in metal. We know what death/black metal vocals are, but the shock has worn off as they’ve been appropriated by other genres. They are not extreme anymore, and overused by those who like them because a plausible imitation is easy to pull off. On the other hand, shouting vocals (Pantera) are annoying, most male singing sounds like drunk guys brawling, and the high pitched “operatic” vocals divide an audience. No vocals, no worries.

Third, this would make it easier to tell real metal bands from the weekenders. Real bands can put together long pieces that make sense, where the weekends just want the appearance thereof. Contrast real progressive rock like Yes to the somewhat paltry substitute in Opeth. Opeth have nailed the aesthetic, but not the underlying musical depth or density. When you hear the two together, it’s clear they are from different genres.

Fourth, instrumental metal would enable greater riffiness in metal. Already there’s a storm of protest when “riff salad” songs emerge, even if the riff makes sense. Much of death metal was an end run around using constant verse-chorus vocals, thus liberating guitars to create more interplay between riffs. Without vocals to keep bringing the song back to repetition, riffs could have greater leeway and repetition would exist not out of standard song form, but to emphasize parts of the song that need repeating for the sake of atmosphere.

Many people out there want metal to go instrumental. While it loses the masculine and terrifying aspect of the vocals, it encourages a competition among metal bands to not only preserve that but make it more extreme among their instrumentals. And if anything, that’s closer to the spirit of metal itself.
